Pennsylvania DUI Laws, Penalties & BAC Limits

A DUI in Pennsylvania — driving under the influence of alcohol or other drugs — is a serious offense that carries substantial legal penalties. If you're caught driving above the legal blood alcohol limit of 0.08, you may face a suspended license, fines and even jail time. The consequences for a DUI in Pennsylvania also increase based on how much alcohol is in your blood and how many DUIs you have previously received.

DUI penalties in Pennsylvania

Driving under the influence of alcohol or other drugs comes with serious penalties in Pennsylvania. Possible consequences include a fine, suspension of your license and even jail time. The repercussions you'll face depend primarily on whether you've gotten a previous DUI and how high your blood alcohol concentration (BAC) was when you were pulled over.

Another consequence of getting a DUI in Pennsylvania is much higher auto insurance rates. Drivers in Pennsylvania are not required to get an SR-22 proof of insurance form as a condition of license reinstatement after a DUI. However, you are still likely to pay much more for car insurance than someone without a DUI, as having a DUI on your record puts you in a higher risk category to insurers. It's even possible your insurance company may cancel your policy after you're convicted.

First-time DUI offense

Even a first DUI offense in Pennsylvania can carry with it serious consequences. Depending on a driver's blood alcohol content, they can face fines between $300 and $5,000, and they may face a license suspension as well.

All first-time DUI offenders are also ordered to enroll in alcohol highway safety classes and may be required to attend sobriety treatment if ordered by a judge.

ARD: Pretrial intervention for first-time offenders

First-time DUI offenders may be eligible for Pennsylvania's Accelerated Rehabilitative Disposition (ARD) program. Under this pretrial program, the consequences of a DUI are focused on rehabilitation rather than punishment.

Opting for an ARD sentence may result in a lessened fine or lower license suspension time, among other potential changes. Additionally, drivers may have their convictions expunged from their criminal record after successful completion of the program.

However, an ARD may not be right for every driver, even if they are eligible. For example, agreeing to an ARD program will result in a driver's commercial driver's license (CDL) being suspended for a year. Only a lawyer should recommend whether accepting a plea under this program is right for your situation.

Second offense

Second-time DUI offenders are subject to stricter punishment under Pennsylvania law. Fine levels are increased, and you are guaranteed to have your license suspended. For their second DUI, drivers in Pennsylvania will also be required to have an ignition interlock on their car for one year, which prevents them from driving if their BAC is over a certain — very low — limit.

Third offense

Third-time DUI offenders are more likely to pay a hefty fine than they were for their first or second time getting a DUI in Pennsylvania. However, similar to a second offense, the fines for a third DUI can reach $10,000.

Additionally, a third DUI with a BAC over 0.16 or under the influence of drugs is considered a third-degree felony, with a minimum jail time of one year.

Fourth and later offenses

A fourth DUI or later is automatically a felony in Pennsylvania, regardless of how intoxicated you are. You're also guaranteed a license suspension of 18 months and a long jail sentence if you have a BAC of over 0.10.

Increased penalties for connected offenses such as fatalities

Besides the consequences of simply being caught driving while under the influence of alcohol, Pennsylvania also has severe punishments for people who cause accidents while intoxicated.

What is the legal limit for a DUI?

In Pennsylvania, the minimum BAC for a DUI is 0.08%, commonly written as 0.08. This is the minimum BAC for a DUI in almost every state; however, Pennsylvania uses a tiered DUI system — the higher your blood alcohol content, the more severe the punishment.

Pennsylvania is an implied consent state: According to Pennsylvania law, drivers have agreed to chemical alcohol testing as a condition of receiving a driver's license. As a result, drivers who refuse a chemical test (either blood, urine or breathalyzer) receive the same punishment as drivers who have the highest BAC rating.

The highest DUI classification is also applied to drivers who drive under the influence of other drugs.

DUI limits for drivers under 21

Drivers who are under 21 years of age are considered to be driving under the influence of alcohol if they test higher than a 0.02% BAC. This means an under-21 driver who has had just one beer could be subject to the same penalties as a driver over 21 who has had three or more drinks.

The financial risk of a DUI can be even higher for young drivers. Besides simply paying more for insurance overall, drivers under 21 also see the biggest increase in car insurance rates after getting a DUI.
